Bochnak, yep, that's me too. I just saw your 3 month old PM, haven't messed with the Chevelle for a long time.

I just logged in to see what trouble I caused here! It doesn't look like anyone changed to a 170 thermostat, that's where the fun starts because the heater is hotter and it still won't heat spike. I got an engineer in the product development lab at Stant to custom make me a couple way back when. But I later found 170 stats off-the-shelf at Summit Racing. Get one of these! Remember to drill a 1/8" bleed hole on the skirt. http://www.summitracing.com/parts/me...0170/overview/

Our kids are all gone and the ProStar hasn't been on the water for 2 years. I rode my bicycles 11,000 miles instead. It's strange how interests change.

Has anyone, instead of capping off existing tube, just plumbed it into new hardware on front? That way steam could travel the least path of resistance and escape either toward the front or rear. Overkill?

That is what I did. I bought a used factory steam tube and put it on the front. I plumbed the rear tube into the hose to the manifold with a brass tee. I figured if it ran too cool, I could block it off later. I did drill another hole in the thermostat to make sure enough water could flow in just to be safe. All said and done, it works great.

Hi Guys,
I just bought a boat with an LT1 a couple of weeks ago. Does it look like mine has the bulletin completed. I wish I had better pics but it is in storage 10 hours away where I bought it.
Thanks,
Eric
